That’s the speed your airspeed indicator shows based on ram air pressure in the pitot tube. Lift, drag, and handling correlate well with IAS in the lower atmosphere. This type of wing redirects the shockwaves further aft on the wing, reducing drag. This is partly due to the steep rise in drag nearing M cr.

Ram air from a pitot tube and static (undisturbed) outside air from a static port, usually a hole on the side of the fuselage. Airspeed indicators need air from a pitot tube and static air from a static port Small general aviation aircraft have airspeed indicators with air hoses connected directly to the pitot and static sources.
